Orkin, the Atlanta-based pest control company, released its rankings of top 50 mosquito cities Monday and Detroit came in just outside of the list's top 10. It also lands three spots down from the previous year's ranking, according to the company.

“Mosquitoes continue to be a major health concern, especially in the summer months,” Chelle Hartzer, an Orkin entomologist, said in a statement. “According to the CDC, vector-borne diseases like Zika virus and West Nile virus have tripled since 2004. These mosquito-borne diseases may have serious side effects."

The rankings are based on the number of its new customers who called for mosquito treatments between April 1, 2017, and March 31, 2018, Orkin said.
